MAINTENANCE GUIDELINES
Maintenance interval
The maintenance of the units should be carried out before the heating period, to ensure correct functioning
of the air curtain.
Cleaning interval
The cleaning of the inlet grilles depends on the contamination of the unit. It is recommended to clean it every
3-6 weeks.
Casing
External staining on the unit doesn't have an impact on the functioning of the air curtain. For esthetical
reasons we recommend to clean the casing with a damp cloth and a mild cleaning detergent.
Inlet grille (filter)
The units are designed for easy cleaning and servicing. It is not necessary to disassemble the unit to clean
the inlet grille. All dust can be removed with a Hoover and a brush. It can also be cleaned with a damp cloth.
Please let the inlet grille dry before restarting the unit!
Heat exchanger
To open the access panel, please remove the inlet grille first by opening the clip fixings with a flat screw
driver. Security ropes prevent the grilles to fall down. The access panel is provided with a security screw that
can be removed after the inlet grille has been detached. Please be careful when removing access panel and
outlet grille.
For security reasons the unit has to be taken off the electrical power supply.
The R410A DX Coil has to be cleaned with a Hoover and a brush
behind the inlet grille.
The fans or motors are low maintenance. All motors are long-term
lubricated and do not need special maintenance. Only check that the
fans run freely and the fixing points are in order.
Recycling
It is possible to recycle air curtains.
